Are fiber optic cables heavy
Optical fiber consists of a and a layer, selected for due to the difference in the between the two. This coating protects the fiber from damage but does not contribute to its properties. While the glass fibers inside are fragile, modern fiber cables are engineered to withstand crushing forces, extreme temperatures, and even rodent attacks—making them vital for harsh environments. This is due to the higher speeds and bandwidth it can provide compared to standard ethernet or Wi-Fi signals delivered via coaxial or even copper wire from street-level exchanges.
